[patch] support 14bit NEF

> Works fine. Applied.
>>> Still one detail left over: why does the size of the picture get offset?
On NEFs the raw_width not being the same as width you mean? Some NEF
files have some form of padding. That and some unit tests for the
classes I have added is next on my todo list.
I will be out until the 13th of August (taking photos instead of
processing them :-) ). Will work on it when I get back.
